Re: Which enclosure do I need for this controller?

You're a woodworker, make a wooden one.  Resaw a block along the
grain, hollow it out, glue it back together with the board inside it.
Otherwise, my only advice is to use a plastic (i.e. non-conducting)
box.

See the thermostats I made out of wood here:
